본 고안은 자동차의 승객용 에어백에 관한 것으로, 특히 에어백의 커버와 크래쉬패드 사이의 갭으로 인한 단차발생을 방지함과 동시에 충돌로 인하여 에어백의 전개시 파단부가 용이하게 찢어지도록 하며, 또한 파단부의 성형작업이 용이한 자동차용 에어백의 장착구조에 관한 것이다.The present invention relates to a passenger airbag of an automobile, in particular, to prevent the step caused by the gap between the cover and the crash pad of the airbag, and at the same time to break the break easily during deployment of the airbag due to the collision, and also to form the break It relates to a mounting structure of a vehicle airbag that is easy to work.
일반적으로 승객용 에어백은 자동차의 크래쉬패드에 장착되어 차량충돌시 내장된 에어백을 순식간에 팽창시켜 승객의 머리, 가슴부위 등 상반신을 보호하는 것으로, 이러한 에어백은 제1도에 도시되는 바와 같이 크래쉬패드(1)에 하우징(2)이 장착되고, 그 하우징(2)의 내부에는 충돌시 팽창되는 에어백(3)이 내장되며, 하우징(2)의 전면에는 스킨(skin)(4)이 부착된 커버(5)가 장착된다.In general, a passenger airbag is mounted on a crash pad of a vehicle to instantly inflate an internal airbag during a vehicle crash to protect the upper body of the passenger's head and chest, and such an airbag is a crashpad as shown in FIG. A housing (2) is mounted to (1), and inside the housing (2) there is a built-in airbag (3) which is inflated upon impact, and a cover (skin) attached to the front of the housing (2). (5) is mounted.
이때, 커버(5)의 상부에는 리벳, 스크류 등으로 하우징(2) 상부에 일체로 고정되는 고정부(6)가 돌출되며, 커버(5)의 하부에는 하우징(2)의 하부에 부착된 인플레터(inflator)(7)에 연결되어 충돌시 파단되는 파단부(8)가 돌출된다.At this time, the fixing part 6 which is integrally fixed to the upper part of the housing 2 by a rivet, a screw, etc. protrudes from the upper part of the cover 5, and the inflation attached to the lower part of the housing 2 is lowered to the lower part of the cover 5. The break 8, which is connected to an inflator 7 and breaks upon collision, protrudes.
한편, 상기 파단부(8)의 선단부에는 인플레터(7)가 연결되는 연결공(8a)이 천공되며, 그 후단부에는 충돌시 파단되는 슬릿홀(slit hool)(8b)이 형성된다.On the other hand, a connection hole 8a through which the inflator 7 is connected is drilled at the tip end of the break 8, and a slit hole 8b is formed at the rear end of the break 8 at the time of collision.
따라서, 이러한 종래의 에어백 장착구조는 인플레터(7)의 단부를 파단부(8)의 연결공(8a)에 삽입하여 고정시켰기 때문에, 인플레터(7)와 연결공(8a)의 유격으로 인하여 커버(5)와 크래쉬패드(1) 사이에 제1도의 가상선과 같이, 갭이 발생하여 단차가 생기는 문제점이 있었다.Therefore, such a conventional airbag mounting structure inserts and fixes the end of the inflator 7 into the connection hole 8a of the fracture portion 8, and therefore, due to the clearance between the inflator 7 and the connection hole 8a. There was a problem that a gap was generated between the cover 5 and the crash pad 1 as in the virtual line of FIG.
또한, 종래의 장착구조는 인플레터(7)에 연결되는 파단부(8)에 연결공(8a)과 슬릿홀(8b)을 각각 형성하여야 하기 때문에 성형작업이 불편하였으며, 에어백 전개시 슬롯홀(8b)이 쉽게 찢어지지 않는 문제점이 있었다.In addition, the conventional mounting structure is inconvenient for molding because the connection hole (8a) and the slit hole (8b) must be formed in the break portion (8) connected to the inflator (7), the slot hole ( 8b) was not easily torn.
본 고안의 목적은 상기에서와 같은 종래의 결점을 해소하기 위해, 에어백의 커버와 크래쉬패드 사이의 갭으로 인한 단차발생을 방지함과 동시에 충돌로 인하여 에어백의 전개시 파단부가 용이하게 찢어지도록 하며, 또한 파단부의 성혀작업이 용이한 자동차용 에어백의 장착구조를 제공하는데 있다.An object of the present invention is to prevent the step caused by the gap between the cover and the crash pad of the airbag to solve the conventional drawbacks as described above, and at the same time to make the fracture easily torn during deployment of the airbag due to the collision, In addition, to provide a mounting structure of the airbag for automobiles that is easy to work on the break.
이하 첨부된 도면에 따라서 본 고안의 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention in detail according to the accompanying drawings.
본 고안은 제2도에 도시되는 바와 같이, 인플레터(10)에 에어백 커버(20)의 파단부(30)를 고정함에 있어서, 상기 인플레터(10)의 하부에 요홈(41)이 형성된 브래킷(40)을 소정의 간격을 두고서 고정하고, 그 브래킷(40)의 요홈(41)에 스프링(51)의 탄력으로 상부가 인플레터(10)에 접촉하는 걸림구(50)를 탄설시키며, 상기 파단부(30)에 인플레터(10)와 브래킷(40) 사이로 삽입되어 상기 걸림구(50)에 고정되는 걸림홈(31)을 천공하되, 그 걸림홈(31)의 일측으로 파단부(30) 두께를 얇게 형성하여, 충돌시 얇게 형성된 부위가 찢어지도록 구성함을 그 기술적 구성상의 특징으로 한다.The present invention, as shown in Figure 2, in fixing the break 30 of the airbag cover 20 to the inflator 10, the groove 41 is formed in the lower portion of the inflator 10 bracket Fix 40 at predetermined intervals, and hold the catch 50, the upper part of which is in contact with the inflator 10 by the elasticity of the spring 51 in the groove 41 of the bracket 40, The hole 30 is inserted between the inflator 10 and the bracket 40 in the break portion 30 to drill the catch groove 31 fixed to the catch hole 50, and the break portion 30 is formed at one side of the catch groove 31. It is characterized by its technical construction that the thickness is formed thin so that the thin formed portion is torn in the event of a collision.
이와 같이 구성된 본 고안은 제2도에서와 같이, 커버(20)의 파단부(30)를 인플레터(10)와 브래킷(40) 사이로 삽입시키면 파단부(30)에 형성된 걸림홈(31)이 스프링(51)으로 탄설된 걸림구(50)에 탄력적으로 고정된다.According to the present invention configured as described above, as shown in FIG. 2, when the breakage portion 30 of the cover 20 is inserted between the inflator 10 and the bracket 40, the catching groove 31 formed in the breakage portion 30 is formed. It is elastically fixed to the catch 50 that is installed in the spring (51).
따라서, 이러한 본 고안은 걸림구(50)와 걸림홈(31)이 유격되지 않기 때문에, 커버(20)와 크래쉬패드 사이의 갭발생을 방지하여 종래와 같이 단차가 생기는 것을 방지할 수 있는 장점이 있다.Therefore, since the present invention does not have a gap between the catching hole 50 and the catching groove 31, the gap between the cover 20 and the crash pad can be prevented to prevent a step from occurring as in the prior art. have.
또한, 본 고안은 종래와 같이 별도의 슬릿홀을 형성시키지 아니하고, 단지 걸림홈(31)의 일측으로 파단부(30) 두께를 얇게 형성하여 충돌시 그 부위가 찢어지도록 하였기 때문에, 파단부(30)의 성형작업이 용이함과 동시에 충돌시 파단부(30)가 용이하게 찢어지는 장점이 있다.In addition, the present invention does not form a separate slit hole as in the prior art, since only a thin portion of the fracture portion 30 is formed on one side of the engaging groove 31 so that the portion is torn during a collision, the fracture portion 30 At the same time, the shaping portion 30 is easily torn at the time of collision.
이상에서 설명한 바와 같이 본 고안은 에어백의 커버와 크래쉬패드 사이의 갭으로 인한 단차발생을 방지함과 동시에 충돌로 인하여 에어백의 전개시 파단부가 용이하게 찢어지도록 하며, 또한 파단부의 성형작업이 용이한 매우 유용한 고안이다.As described above, the present invention prevents the step difference caused by the gap between the cover and the crash pad of the airbag, and at the same time, the break part easily tears when the air bag is deployed due to the collision, and the molding work of the break part is very easy. It is a useful design.
